I was wondering if it would be safe to drive my car while keeping it under 3k rpms to the shop to get it tuned. My car already has a basemap from my old setup but ive changed quite a bit since then, before was just a stock b18c1 witha drag kit, now i have a bigger turbo, bigger intercooler, 750cc injectors, and a built b16a2 block. Would it be better to run it with the old 440cc injectors that the base map was tuned on? any help is appreciated, thanks btw the blocks not brand new its already been broken in on the dyno has 300 miles on it

 

The 450cc map will not run the 750cc injectors. The only way you can work around this would be to play with your fuel pressure.

 

get the 450's back in, stay away from boost (low rpm) and keep an close eye on your wideband.... that's the only way i'd be comfortable enough to go out and drive to the dyno
